Abstract: A method in a proxy call session control function, P-CSCF, of handling an unauthenticated emergency call originating from a roaming user equipment, UE, which is not attached to the P-CSCF. The P-CSCF receives a SIP INVITE request from the UE, the INVITE request relating to the unauthenticated emergency call, and determines an IP address of the UE. The P-CSCF sends an identity query to a policy and charging rules function, PCRF, indicating the IP address of the UE and requesting other identifiers of the UE, and receives one or more other identifiers of the UE from the PCRF. The P-CSCF constructs a TEL and/or SIP uniform resource identifier, URI, for the UE on the basis of at least one of said other identifiers, inserts the URI into the SIP INVITE request, and sends the SIP INVITE request to a public safety answering point, PSAP. Also provided are corresponding methods in other nodes and for authenticated emergency calls, and apparatus for implementing the methods.

Abstract: A wireless device receives, from a base station, message(s) indicating: a counter value(s) for a counter(s) of SR configuration(s) of the base station. Each SR configuration corresponds to a logical channel. SR(s) corresponding to an SR configuration(s) may be triggered in response to data becoming available to their logical channel(s). Counter(s) may be set to an initial value in response to no other SRs corresponding to the pending SR configuration(s). A random access preamble is transmitted to the base station in response to counter(s) reaching their counter value.

Abstract: A method implemented by a station (STA) in a Wireless Local Area Network (WLAN) to disregard a Network Allocation Vector (NAV) maintained by the STA. The method includes receiving a first Physical Layer Protocol Data Unit (PPDU) from an Access Point (AP), where the first PPDU elicits an immediate response from the STA, determining whether the NAV maintained by the STA was previously set using a duration indicated in a second PPDU that originated from a same Basic Service Set (BSS) as a BSS that the STA is associated with, and transmitting a third PPDU to the AP as an immediate response to the first PPDU without regard for the NAV maintained by the STA in response to a determination that the NAV maintained by the STA was previously set using the duration indicated in the second PPDU that originated from the BSS that the STA is associated with.

Abstract: Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.
